SPECIFICATION forming part of Letters Patent No. 659,075, dated October 2, 1900.

Application filed July 29. 1899- o'erial No. 7251481. (No model.)

To all whont it nwty concern:

Be it known that I, WILLIAM -HAMMOND LEISTER, of Westminster, in the county of same side of the other end of the machine,

the two figures joining, respectively, upon the right and left margins thereof. Fig. 3 is a side elevation of the extended portion of the can-rack, which is broken away at the right of Fig. 2. Fig. 4 is a top plan view of the mechanism which is placed above the can chute or track. Fig. 5 is a top plan view of the can chute or track. Fig. 6 is a longitudinal sectional elevation of the can chute or track and the mechanism for applying adhesive material to the can and label. Fig. 7 is a top plan view of the tank and mechanism which applies adhesive material to the can in order that it may take up a label, the cover of the tank being removed. Fig. 8 is a side elevation of the upper end of the frame carrying the paste-reservoir P and the belt by which the paste is applied to the labels. Figs. 9 and 10 are elevation and plan views of the canreceiving table, which is broken' away at the left of Fig. 1. Fig. 11 is a cross-sectional elevation taken through the can chute or track, showing the method of adjusting the same laterally; and Fig. 12 is a cross-sectional elevation of said'chute or track, taken through the sockets which contain the label-holding hooks.

This machine belongs to that class in which the cans are rolled along a chute or track and are successively operated upon, whereby a portion of the adhesive material is applied to the can, and the can is then rolled upon a pile of labels, picking up the upper label by said adhesive material and then wrapping the label about the can, the other end of the label being pasted so that as it is wrapped about the can it will be secured in place. I

The main bar A of the framework extends substantially in the same direction and par allel with the tracks upon which the cans roll. This bar is supported upon bars A and A located at each end thereof, said bars being supported from a low table or frame consisting of bars A and the legs A said frame being braced by means of diagonal braces A At each end of the bar A and at such ot-her points as may be found necessary are provided supports for the track-bars B, said supports being constructed after the manner shown in section in Fig. 11. The bars B, forming the'track or chute, have laterallyextending pins or bars I), secured thereto and extending into sockets Bflformed within posts B placed upon the frame-bar A. The socket B is larger than the pin 1) and receives a spirally-coiled spring I), which surrounds the pin 7). This spring serves to force the trackbar B away from the frame-bar toward the center. This action is resisted by means of a thumb-nut 12 which screws upon the outer end of the pin 1). As many'of these supporting-pins as are necessary are provided. I have herein shown two for each bar, one located at each end thereof. The bars B serve simply to support the cans. The cans are guided in the proper course upon the trackbars by means of bars D, which are supported above and outside of the track-bars, being adapted to engage the ends of the cans and restrain them against side motion. These bars are also made adjustable in a manner somewhat similar to that used for the trackbars B. The barsD have lateral projecting pins D, which pass through holes in posts or brackets D which extend upwardly from the chine. For convenience and to keep the machine within reasonable limits this receivingtrack has been made into two sections, one located above the other, both sections being inclined, but in opposite directions. The lower section E is secured to one end of the frame-bars A at E and is supported by means of-a brace-rod E, which at its upper end is pivoted to bars E, forming the lower portion of the receiving-track, and at its lower end is adapted to engage the frame of the machine in any convenient manner, as by entering a socket or hole formed in said frame. The upper section E of this track is supported on the lower section by means of bars E and E. The outer ends of the bars E, forming the lower section, are curved upwardly, as shown at E in Fig. 3. The space between the outer end of this bar and the corresponding end of the bar E is suflicient to permit a can to pass between. The cans are placed upon the upper section, as indicated by dotted lines in Fig. 2, and roll down the same until they come to the opening between the ends of the bars E and the curve E when they drop to the lower section and pass down upon the same to the can-chute upon the machine. As they strike this can-chute they are engaged by the feed-wheels H These wheels are preferably provided with a. rubber band or covering, which will engage the cans. The wheels H are mounted upon the ends of a transverselyextending shaft H, which is journaled within the outer or swinging end of a link or bar H, the other end of such link or bar being pivoted upon a transversely-extending shaft a, which is placed in the upper end of a standard a, supported upon the frame-bar A.

To the standards (0 are secured two arms H which extend in opposite direction therefrom and longitudinally of the machine. On the outer ends of these arms are secured vertical bars H by means of set-screws h, which pass through slots in said bars, so that the bars H are adjustable in elevation. The upper ends of these bars engage, respectively, the link or bar H and a corresponding link or bar h, which extends oppositely from the bar H. By adjusting the bars H the links H and 71 are raised or lowered and the wheels carried thereby adjusted to correspond with the different'sized cans. These links or bars H and h are held downward by gravity and by the action of a flat plate-spring H, which at its central point is secured to a bar connecting the upper ends of the standards a. The link h, which forms the frame carrying the wheels 7L2, is pivoted upon the same shaft a as that carrying the link H. Each, however, extendsin an opposite direction. The wheels 7L2 are similarly provided with rubber bands or tires about their peripheries, so that they will engage the cans without slipping.

Keyed upon the shaft (1 are two grooved pulleys H and k Upon the shaft H is also seen red a grooved pulley H which is in line with the pulley H About these two pulleys passes a belt H so that the two shafts are turned together. The shaft 7t also has a grooved pulley 71 secured thereto and a belt 72, passing about the same and the grooved pulley h. The sizes of these pulleys are such that the shaft 77. and the wheels carried thereby are rotated much more rapidly than the shaft H and the wheels carried thereby. The wheels W are accelerating-wheels, being designed to engage the cans and accelerate their rolling movement upon the can chute or track. Cans coming down the inclined track IE will first engage the wheels H and will be fed beneath the same at a rate corresponding with the speed of the rotation of the said wheels. These Wheels, therefore, act as regulating and feed wheels, determining the rate of feeding the cans.

While passing beneath the wheels H the can is operated upon by a device which applies a small amount of cement or adhesive material to the can, so that the can may be enabled to secure one end of the label thereto when it rolls upon it. The tank F, which contains the adhesive material, is located beneath and between the frame-bars A and the track upon which the cans roll. This tank is shown in cross-section in Fig. 6. It is made with one end a little lower than the other, so that the cement or adhesive material contained therein will flow toward this end and make it possible to more nearly use up all the material in the tank than would be possible if the bottom of the tank were level. Within the tank is pivoted a lever or frame g by means of a pivot g, located at the end of the tank where the bottom is highest. This frame carries two springwire arms 9 upon the outer ends of each of which is placed a pad or small hammer g Near the opposite or lower end of the tank is pivoted a lever G one end of which passes beneath the frame g, so that when the opposite end of the lever G is depressed the frame g will be raised, carrying upward the pads 9 Upon the short end of the lever G is secured a plunger-rod, which is made in two parts, consisting of sections G and G, thelower section G being pivoted to the end of the lever G and the upper section G passing through the hole f in the cover F of the tank The adjacent ends of these two sections are reduced in size and a spirally-coiled spring G is placed aboutthe same. This spring will normally hold the two sections separated and make the device yielding, so that the bars need not be adjusted as accurately in their movement as would otherwise be necessary. The power for depressing this plunger is mainly derived from the wheel H acting through the can. The cover F of this tank is preferably made slightly concaved on its upper side, so that any cementorpaste which may drop thereon will flow to the center. The cover is also inclined in the other direction and is provided with a slotf near its lower end, through which the cement or paste which may collect upon the cover may flow hack into the tank. The cover is also preferably provided with a flange F extending about its edge and preventing the escape of any cement from the edges of the cover. The spring-arms g which carry the pads 9 are guided laterally by means of ribs f placed within the tank. The cover F of the tank is provided with two holes f, located one at each side thereof and so placed that the pads or hammers 9 when they rise by reason of the depression of the plunger G will be projected through these holes, and thus come in contact with the lower side of the can which has just passed over and depressed the plunger G. The upper endof the plunger ordinarily projects above the track, so that the can as it passes down the track will depress the plungerand cause the pads g to be raised into contact therewith, thus placing two small spots of cement or adhesive material upon the outer surface of the can. The tank is made readily removable from the frame in order that it may be filled when necessary. On its lower side it is provided with one or more longitudinallyextending flanges F, which fit within grooves formed in a plate F which is supported from the frame-bar A by means of the bars F located one at each side thereof. The tank is clamped in position by means of set-screws F which pass through said bars F and engage the outer surface of the tank.

The tank F is kept heated by means of a torch T or any other suitable device located beneath the same. The torch herein shown is of that general type which uses gasolene or similar fuel and compressed air for forcing the same to the burner. This form of torch is in common use by electrical workers. The tank T of saidtorch is held in place upon a stand T by means of a set-screw T which engages one side thereof, the other side being held by a flange upon the stand. This stand is supported by a bar T from the lower frame-bar A.

The labels L are placed in the machine in a large bundle or pile. These labels are supported upon a plate C, which in turn is carried by posts O, which are mounted to slidein suitable guides in the framework. The plate 0 in its depressed position is adapted to lie upon the plate 0, which forms a portion of the framework. This plate 0 is supported upon bars A which at their lower ends are secured to the frame-bars A. The plate C is also connected with the upper framebar A by means of bars A which pass up ward alongside of the labels. The labels are restrained in position upon the label-plate O by means of the bars A which at their up per ends are secured to the inner edges of the track-bars B by being notched into the same, so that the outer surfaces of the bars A and the track-bars B are flush, as shown at A in Fig. 5. The lower ends of the bars A are connected by a transverse member,

which has a central depending arm U, the lower end of the arm being bent horizontally and projecting toward one side of the machine. This lower portion of the bar or extension U is slotted longitudinally or in adirection transversely of the machine, and it is secured to the plate 0 of the frame by means of a bolt and clamping-nut, whereby it is made adjustable transversely of the machine to correspond with labels of different widths. The ends of the labels are kept in correct position by means of a bar G which extends upwardly from the end of the plate C to near the top of the pile of labels. The lower ends of the posts 0 which support the label-plate are connected by a crossbar or plate G which is connected with a link 0 the other end of the said link being pivotally connected to the outer end of the spring-bar C The opposite or fixed end of the springbar 0 is secured to an arm 0 which projects downwardly from the frame and is rigidly secured thereto. This spring is of such strength that it will support the pile of labels and force the label-plate, with the labels thereon, upwardly, so as to keep the top of the pile in a fixed position. When the spring is in its lowermost position, as when a pile of labels has been just placed in the machine, it is exerting the most strain which is required, as the weight of the labels is the greatest at this point. As the labels are consumed their weight decreases, and the strength of the spring correspondingly decreases as it is moved upward, which is-due to the consumption of the labels. The tension of the spring may be adjusted by means of a bar 0 which is secured by a screw or bolt 0 to the lower portions of the arm O". The lower portion of this bar, through which the screw C passes, is provided with a slot receiving the screw C so that the bar may be adjusted to contact the upturned end thereof with the spring C at different distances from its support, thereby varying the tension of the spring. The labels are limited in their upward position. by means of a roller L, which is journaled in the framebars A and which extends across one end of the labels. The labels contact with the lower edge thereof near their ends. This roller prevents the labels from rising too high and also enables the labels to be easily pulled from beneath the same as they are attached to the cans. The can after having a small amount of adhesive material or cement applied thereto by the mechanism contained within the tank F rolls downward upon the track or chute until it drops upon one end of the pile of labels, said end being the free end, or the one opposite that which is held down by the roller L. The distance between the point where the cement has been applied to the can and the point where it drops upon the labels is such that the can has made one complete revolution. It will therefore drop upon the labels with the spotted side or that containing the cement downward. The label will therefore be well attached to the can, so that as the can continues its forward movement the label will be wrapped around the can. The track at this point is provided with a drop, as shown at V in Fig. 6. The point where this drop commences is varied by means of a slide 4), which consists of a plate forming a short section of the track and provided with a slot c, through which passes a clampingbolt 0 The end of the plate I from which the can drops is curved downwardly, as shown at '0 The label having been attached to the can and rolled about the same passes beneath a smoothing device consisting of a springplate M, which is supported from standards M, secured to the frame of the machine at such a height thatit will lightly engage the upper side of the can as it rolls beneath. At about the time the can drops into the depression V in the track it is engaged by the accelerating-wheels 71. so as to cause it to move more rapidly along the track. This insures also that it shall be forced into the depression V in the track, and thus be brought into contact with the labels. At a point near the roller L two sockets are provided in the track B, one upon each side of the machine. These sockets contain a block b which is provided with a hook-arm b, projecting toward the center of the machine. The sockets are open at their inner edge or provided with a slot adapted to accommodate said hookarms. Blocks b are held down by means of a spiral spring b which in turn is held by a threaded lug which screws into the upper end of the socket. These hook-arms lightly engage the upper label of the pile near its edge and prevent the same from being removed without the application of a little force. As the label is wrapped about the can the can will in its forward movement break the label from beneath the hooks, thus making a slight tear in the edge of the label. If this is deemed undesirable, the hooks may be rounded at their points, so that the label will be pulled from beneath the same without tearing. Just before the label is removed from the pile the end thereof is coated with paste, so that when it is wrapped about the can it will stick in place. The means for applying the paste is shown in Figs. 1 and 6, Fig. (3 being a section thereof. A standard A forms a portion of the framework of the machine and is curved so as to receive the paste tank or reservoir-P. This tank or reservoir has an arm P upon each end thereof on W- ing upward and backward and slotted at its end. Said arm is adapted to slide between two guideways aflplaced upon the side of the standard A. A clam pin g-bolt a passes through the slot in the arm P and secures the bar to the standard. The frame is secured by or formed as a part of the paste-tank, said frame containing the standards P to the upper ends of which are secured the bars P, which extend at an angle to the horizontal, the upper end thereof extending to very near the roller L. In the upper outer end of the bar P are formed two bearings adapted to receive the journals of two rollers O O. The bearing for the journal 0 consists of a notch extending inward from one edge of the bar, so that the roller 0 may be readily removed therefrom when desired. The bearing for the other roller 0 consists of a vertical slot, whereby the roller is permitted to have a limited vertical movement. Within the paste tank or reservoir P is journaled a roller 0, and a fourth roller 0 is journaled upon the bar P above the tank. About these various rollers passes a belt 19, which dips beneath the paste in the tank and thus becomes coated. This belt passes about the roller 0 as a loop and passes above the roller 0 said roller 0 simply engaging the outer surface of the belt. This leaves a short section of the belt at p in position to be engaged by the upper surface of the uppermost label in the pile. The roller 0 is located immediately above the end of the pile of labels. Depending from the bar I of the frame is an arm P to the lower end of which is pivotally secured a fork R, the two prongs of which extend upon opposite sides of the belt and act as a scraper to remove surplus paste from the belt. This fork is secured in position by means of a clampingbolt or set-screw R. The fork may thus be adjusted by twisting on its pivot, so as to bear lightly or hard upon the uprising section 12 of the belt, as may be desired. The roller 0 is provided upon one end with a ratchetwheel 0 which is adapted to be engaged by a pawl Q, to turn the same. This pawl is pivoted upon one end of a lever Q, which in turn is pivoted at Q upon the main frame of the machine. The pawl Q is held in contact with the ratchet-wheel by means of a counterweight Q upon its upper end. The lever Q is vibrated to turn the ratchet-Wheel O by means of a link K which is operated in a manner hereinafter to be described. After the can has passed beneath the smoothingplate M it is engaged by a belt I, which passes over two drums I and J. These drums are mounted above the track in a common frame I. This frame I is mounted to swing upon a shaft J, which forms a shaft for the drum J to turn upon. The drum I is mounted upon a shaft I, which turns in the outer end of the frame I. The drum 1 drops downward under the influence of gravity and is limited in its downward drop by having a projection upon one side of the frame I engaged with the upper end of a post or standard K, projecting upwardly from the main frame of the machine. The swinging frame I is also held downward by means of a spring K, which is secured to the standard K and the frame I. The belt I is an elastic belt of rubber or similar material, so that as the can passes beneath the same it will press firmly upon the entire surface of the can, even if it should happen to be somewhat irregular in outline by having been dented, and it will thus insure that the label be smoothly pressed to the surface of the can. Upon one end of the shaft J is secured a gear- Wheel N, which meshes with a pinion N, mounted upon a shaft N, which is supported upon the outer end of an arm 1 Upon the shaft N is also secured a fly-wheel N by which means the rotation of the mechanism may be made sm oother and more regular than if unsupplied with a fly-wheel. Upon the other end of the shaft J is secured a crank J by means of which the shaft may be turn ed. In lieu of the said crankapulley may be provided,upon which a power-belt may be placed. Upon the shaft J is also placed a grooved pulley or wheel J which is in line with a similarly-grooved wheel J placed upon the shaft a at the other end of the machine. About these two pulleys passes a belt J by means of which power is communicated to the shaft J and to the mechanism at the other end of the machine. By arranging the pastebelt and pressure-belt with respect to each other and to the pile of labels, as shown, and operating the paste-belt from the swinging frame carrying the pressure-belt the pastebelt will be moved at the time the label is being drawn by the can from under the pastebelt, and the belt and label moving in opposite directions will cause the paste to be rubbed into the pores of the label, rendering it soft and permitting it to be firmly and smoothly pressed upon the can. The cans after being engaged by the belt I are rolled beneath the same and the label securely smoothed upon the can. They then roll off of the track B upon the track composed of two channel-bars e, which are secured to one end of the machine.= From these two bars they roll upon the filling-table, which consists of a board e and the edges of this board are provided with notches e of a size corresponding to the size of the cans, so that when the board 6 is filled with cans the notches 6 will lie immediately beneath the cans. This makes it easier to grasp the cans for removal than when the edges of the board are straight, as the can ends will lie directly over the notches. A stop is provided at the outer end of the delivery-table and consists of a roller 6 supported at a slight elevation above the belt. This table is supported in position by means of a brace c, which is secured to the table and to the lower portion of the legs A Casters are provided on the lower ends of the legs A as shown in Figs. 1 and 2, so that the machine may be readily moved about from one place to another, and thus be brought close to the pile of cans, thus facilitating the operation of labeling.

In order to move the machine about conveniently, handles S are secured to the framework at convenient points. I

An alarm device is provided which will give notice when the labels are about exhausted, said alarm device being shown in Fig. 1.

To the lower side of the plate or bar 0 is secured a bent arm Vi, upon which is mounted a hell or gong W. The spring-arm, which carries the hammer W is secured to the arm W and is normally held raised above the gong by means of a hook-bar W, which is pivotally secured to the lower portion of the bar or plate 0 or to the arm W as desired. As the label-plate O rises. d ue to the consu m ption of the labels, the cross-bar 0 which connects the lower end of the post G, rises with it, and a pin W which is secured thereto, rises until it engages with the hooked bar W to move the same to one side and free the spring-hammer arm, allowing it to fall upon the gong and sound the alarm.

As the cans pass beneath the drum I it is slightly raised, but drops back as the can passes from beneath it. This acts,through the connection of the link 10 with the frame I and lever Q, to turn the ratchet-wheel O and the pasting mechanism. For convenience in putting in place a new supply of labels a device for holding down the la bel-plate C is provided. From beneath the plate or bar G which forms a part of the frame, depends a rod X, which has its lower end enlarged, as shown at X. This rod passes through ahole in the cross-bar G which moves with the labelplate. When the label-plate is forced downward sufficiently, the lower end of this rod will clear the bar C and engage its upper surfaces, holding the label-plate down until it is freed by hand. From the point where the end of the label is pulled clear of the roller L, the can makes a half-turn before reaching the large roller or drum J, which thus brings the ends of the label beneath and in contact with the drum, causing the label to be seamed by the pressure of the elastic belt and the drum thereon. The springs Y, which form that portion of the track just beneath this drum, will give to allow the cans to pass beneath the drum. This drum is used particularly to seam the label and might be called a seaming-drum? Having thus described my invention, I
